Jacintha Beena Mathias

Data Analyst with two years of experience supporting Shell's reporting systems through Wipro. Worked with pricing, sales, margin and volume data across multiple European markets, using SQL, Excel and MS Access to investigate reporting issues, validate data and support business users. I recently completed an MSc in Data Science at the University of Bristol, where I worked on projects involving machine learning, financial market analysis, healthcare data and interactive data visualisation.

I enjoy solving data problems, understanding why issues occur and using data to support better decisions.
